Claims. 1

This invention relates to machine molding of blocks for building construction for blocks made of cinders, waylite, pumice, sand, cement and other similar materials and also of stone for backing, and in particular a machine of the stripper type where blocks are cast in a mold face down, vibrated, and then turned completely over and ejected vertically from the mold.

The purpose of this invention is to facilitate machine molding of blocks for building construction and to provide a stripper block machine where blocks are cast face downward in a solid rectangular shape mold and ejected from the mold in rapid succession as the position of the mold is inverted.

The usual stripper block machine, being stationary, makes it necessary to cast the blocks with the face on one side and for this reason only plain blocks can be made. In the old style face block machine blocks are made face down and of just damp material, which makes a very Weak block. Machines of this type open up all around and pull mate-rial off of the body of the block should wet material be used. In the machine of this invention wet material is used for strength and the block is stripped out of the mold, making rock face down and turning the mold and block over for removing the block. With this thought in mind this invention contemplates a machine molding process for cementitious materials wherein the blocks are poured with forms in an inverted position or with the face downward and vibrate-d in this position, and then inverted so that the blocks may be ejected from the mold by a vertical upward movement.

The object of this invention is, therefore, to provide means for forming a mold for casting concrete blocks and the like wherein lower forming plates are secured in the mold by inwardly extended flanges on end members hinged to the ends of the form when the position of the mold is inverted.

Another object of the invention is to provide a machine for operating a concrete block mold wherein the block may be cast and vibrated in the inverted position and then turned over to an upright position for ejection from the mold.

A further object of the invention is to provide an improved concrete mold in combination with a machine for operating the mold in which the machine and mold are simple and economical construction.

With these and other objects and advantages in View the invention embodies a rectangular shape stand having a block forming mold thereon, a support plate in the upper part of the frame positioned to receive the mold for casting, means for vibrating the plate, and a manually actuated projector mounted on the side of the frame on which the mold i held, and positioned to be actuated upwardly through the mold for ejecting blocks cast therein.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

The end walls I9 and 20 f the mold frame II] are provided with projections 30 and 3I that form handles and these projections extend through openings 32 and 33 in end plates 34 and 35, respectively, positioned against the ends of the other on a pin 44 extended outwardly from the sidewall 28 of the mold. The opposite end of the end plate 34 is provided with a knob 45 by which it is held inwardly in the position shown in figure by hand when the mold is turned. The end plate 35 which is provided with flanges 46 and 41 is pivotally mounted by a pin 48 in the lugs 49 and 50 of the mold with the pin extended through a lug 5I on the plate and also through the flanges 6 and 41 thereof. This plate is provided with a knob 52 and a spring 53 carried by a pin 54 and attached to a projection 55 of the plate resiliently holds the plate outwardly away from the end of the mold, as shown in Figure 6.

The flanges 36 and 46 of the end plates overlap the ends of a pallet 56 and secure the plate in position against blocks 57 and 58 in the mold when the mold is turned to the inverted positions shown in Figure 3. A face plate 59 with a rock design thereon is secured in the opposite end of the mold by the flanges 31 and ll.

The end and side walls of the mold may be provided with slots 50 as indicated by the dotted lines in Figures 14 and 15 and partitions 6| may be extended across the mold with projection 62 and 63 thereof positioned in the slots 60. The mold may, therefore, be used to form one continuous block or a plurality of blocks may be formed therein and the blocks may be of different sizes.

The mold is pivotally mounted on the shaft 23 and the shaft is carried by the bearings 24 and of the cross bar 26 at the ends of the rails 21 and 28, and the rails are resiliently suspended A vibrator shaft 75 is suspended below the plate I3 of the vibrator elements I2 by channels Ti and 18 with the shaft mounted in bearings "I9 and 80 on the lower ends of the channel, as shown in Figure 8.
